本文件规定了从硬化混凝土中取芯的方法、检验、试验准备和抗压强度测定。 本文件未对钻取岩芯的决定或钻孔位置提供指导，也未提供解释岩芯强度结果的程序。 建议在取芯之前，各方应就岩心测试的必要性以及结果的解释达成全面一致。

This document specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength. This document does not give guidance on the decision to drill cores or on the locations for drilling and does not provide procedures for interpreting the core strength results. It is recommended that before coring, full agreement should be reached by all parties on the need for core testing and how the results should be interpreted.
